Hi
Perhaps the resason that you didn't receive a lot of feedback on the Wine Users Guide is that it is very well written. Nevertheless I have found a few details that might be better explained:
1.2.3 Wine capabilities ..... Notes [1] Today VMware server is free software and you can easily manage a Windows system on a VMware virtual machine. However this does not solve the problem with having to maintain/support two differnt operating systems (quite time consuming...). There is also the commercial software /2X application server/ and /2X application server client /(2X.com) with which windows applications can be run on Linux in single windows using Windows Terminal services. The above 2X software is free up to 5 server connections, for more you have to pay a license fee. So far it is quite beta-style but eventually it might be very good... Windows terminal services is available in Win XP prof, Win 2000 Server and Win 2003 Server (don't know about Vista).
2.2. Getting a Wine package I think you should mention Ubuntu - thera are packages for Ubuntu avaialable on sourceforge.net Wine download page.
That was all for the first 4 chapters - perhaps I'll come back with more feedback later.
